On the development side, if you're into things like visualization and interactive information design, statistics and financial mathematics, finding and cleaning up data, metadata and search systems, machine learning... then we should talk. We're also interested in speaking to prospective business development interns. Email me - email@example.com.
I used to be the developer for Bloomberg's CIX (an excel like language for historical & real-time financial time-series calculations) so it's always interesting to see new people in the space :-)
I'm based in London as well, so if you'd fancy grabbing coffee or something sometime feel free to shoot me an email.
